Prepare water bath canner, about 8 pint jars & lids
Mix 1/4 cup lemon juice with 4 cups water in a large bowl and set aside. This will be used to treat the apples for browning.
Wash, destem and quarter apples. Place in lemon water.
After a few minutes, remove the apples from the lemon water and place in a stainless steel pot (I used an 8 quart). Barely cover apples with water.
Bring to a boil over medium-high heat. Once boiling, reduce heat and boil gently until apples are just fork tender (about 8-10 min). Using a slotted spoon or spider scoop, remove the apples from the water and allow to cool for a few minutes.
Transfer apples to a food mill, working in batches. The food mill will remove the skins, cores and seeds and you’ll be left with a nice apple puree.
Place your apple puree back in stainless steel saucepan. At this time, you can add sugar, if you are using it. (I do not use additional sugar)Add the remaining 1/4 cup of lemon juice to the apple puree. Bring to a boil over medium-high heat. Make sure to stir frequently to keep the applesauce from burning or sticking. Reduce heat to simmer and prepare to fill jars with the simmering sauce. Ladle hot applesauce into your pint jars, leaving 1/2″ headspace. Remove any air bubbles. Add/remove applesauce to reach 1/2″ headspace.Wipe rims with a clean towel moistened with a little vinegar. Center lid on jar and add ring. Screw down to finger-tip tight. Place jars in water bath canner and cover with at least 1″ of water. Bring to boil. Process pints for 20 minutes.
Once the 20 minute processing time is up, turn off heat, remove lid and wait 5 minutes. Remove jars, cool for 16-24 hours.
Remove bands after cooled and wipe jars to ensure there is no residue on them before storing them.
